Manual Support Generation

This manual process will allow you to generate struts as support and for cross-bracing in place of auto-generated supports.

NOTE: When used in a non-stacking workflow, struts can only be generated within a single part (not between two parts).

Use the following guidelines when doing this:

  1. Keep in mind the keyboard shortcuts seen here. The most useful here will be ctrl+click and the spacebar. And read through the best practices of creating struts.
  2. Use default settings for optimal support removal and stiffness. Parameters are open for you to change when optimizing your stacked print. Adjust Normal should be on to make support tips normal to the surface. This prevents supports intersecting a surface at an off angle, which would create larger cross-sections than desired when removing supports.
  3. Click on View on the top right, and check the Down Face box under Shading. This allows a color visualization of down-facing regions to avoid under-supporting when manually creating your supports.
  4. Start between the first and second row of parts when creating your struts. Use ctrl + Click and select two points to generate your strut.
    1. You can create struts on or between struts.

    2. The spacebar is the shortcut key for generating/applying struts quickly.

    3. Check that the angles of the struts are self-supporting. To be safe, 40°-90° from the horizontal should be fairly self-supporting; otherwise, use a strut for support.

    4. With down-face visualization on, you can generate struts to support the down-facing regions and any initial layers of a part.

    5. When struts are created, that strut will be replicated across the entire array. The struts will also be replicated between the first row of parts and the base using the initial point on the top part and the trajectory of the strut. The strut will then find the close point on the base on which to connect.

    6. Repeat these steps until your parts are fully supported.
